摘要：<p>The hydraulic servo steering system has a pump and a pump drive motor, which is operated alternatively in a defined high power level (C), in a defined low power level (B) and in a defined auxiliary power level (A). A controller is provided for making a change in the low power level from the auxiliary power level by gradually changing engine speed (n) or by increasing the speed of the engine. An independent claim is also included for a method for controlling a pump drive motor of a hydraulic servo steering system.</p>
